The NWS confirmed Wednesday that Dayton has hit exactly 95 degrees in air temperature a number of times in recent years (including four days in June-July 2022), but that’s been the peak. It hasn’t been hotter than 95 degrees in almost 10 years — since a 96-degree day on Sept. 10, 2013.
The last time Dayton’s air temperature exceeded 100 degrees was in June and July of 2012, according to the National Oceanic and Atmospheric Administration’s online weather data. That year, it hit 102 on June 28, then stayed in the 90s for a full week, hitting 98 and 99 multiple times, then rose to 102 again on July 6 and July 7.
The only times in the past 40 years that Dayton has gone over 100 degrees for air temperature were those three days in 2012, and seven days in the summer of 1988 (June 25, July 7-8-9, July 15-16, and Aug. 17).
